6 years and now it's renewed. But the last encounter of this sort,quite some time ago. 23 years. That time was a bull - a minotaur - and a triangle,and a mound, and an arch. A power beam, supercharged.

This time was a 6-sided star, and a dome. The energy grid -lines of convection in great circles, plus an axis in and out.

Why are we here? Gysin asked. No why, we are here to go.23 years waiting for 2nd contact. Where's the ignition?Which one's the key?
